解釋
復合場-
While carrying out the scheme, at first, the basic theory of antenna, array antenna and electromagnetic absorption, the performance parameter of antenna and parabolic antenna are deeply researched. in conformity, the characteristic and calculation of aperture field and near - to - far - field transformation for radiation pattern are detailed analyzed. second, the factors such as, the amount of the antenna elements, mutual coupling between each element, ground and the buildings on earth ' s surface, which affect the performance of array antennas ’ resultant field are stressed discussed
在系統實現過程中，課題首先從天線、陣列天線，以及電磁場計算方法的基本理論著手，分析了天線與拋物面天線的各項性能參數，以及天線的口面場和近-遠區輻射場的特點和計算;進而，更加深入的討論和研究影響天線陣列合成場強的各項因素，包括系統所使用的天線單元個數對陣列合成場的影響、天線單元之間由於互耦造成的影響、傳播過程中地面和/或地面建築物的影響等。 -
The resultant electric field will be asymmetric and vary along specific direction when asymmetric electrode strips or multi - phrase driving is employed, which cause flow accelerate. that is the essential of paraelectric and peristaltic. 3
採用非對稱的電極分佈或者在對稱分佈的電極上施加多相位的激勵電壓，合成了一個非對稱而且是沿著某個方向變化的電場促使流動加速，這就是順電加速效應和蠕動加速效應的本質。 -
The resultant change images obtained by the two change detection methods were overlaied to obtain more accurate change information. the analysis of the change information indicates that land use in changle have changed greatly in the study period. the land use change mainly occurred in paddy field, forest, dry land and barren land
本文選取了1998年與2000年的tm / etm和spot遙感圖像，分別採用分類后比較法和光譜直接比較法對長樂市1998 2000年的土地利用進行變化信息提取，再通過兩者的疊加分析最後確認土地利用變化的信息，獲得較為理想的變化監測結果。 -
In this thesis, the overall scheme is to establish a circular array system which is formed from units of parabolic antenna. then, the resultant field will be detailed studied, in order to find out a steady - going array antenna system with the best combined efficiency
本文的主要內容是，利用拋物反射面天線組成圓形陣列，並對該天線陣列的空間合成場問題進行研究，力求在實際應用中得到穩定的、合成效率達到最優的空間合成場。
